Rescale

Purpose

Scales data back to original scaling.

Synopsis

rx = rescale(x,means,stds,options)

Description

Rescales a matrix x using the means means and standard deviation stds vectors specified. An optional input options is an options structure with the field: rx = rescale(x,means) rescales a mean centered matrix x using a vector of means. rx = rescale(x,means,stds) rescales an autoscaled matrix x using a vector of means, and vector of standard deviations stds.

Options

• stdthreshold: [ 0 ] scalar value or vector of standard deviation threshold values. If a standard deviation is below its corresponding threshold value, the threshold value will be used in lieu of the actual value. A scalar value is used as a threshold for all variables.
